Crab, we enforce the "between flight" You land and shut down =you check! This does not take time(1-2 min) or a brain surgeon, but it does bridge the question of "when is the last flight of the day?" It does ensure a crew being able to hand over a aircraft with knowledge and not assumptions.(they had to land to hand over) Again. the new crew will double check aaand it is not to question the previous crew. Different eyes sees differnt things!
